Nishith Sai Namala

Java backend developer. I build things that have to survive concurrency, not just pass a demo.

What I've built

ReserveShow — Movie ticket booking API Solves double-booking under concurrent requests using PostgreSQL pessimistic row-level locking. JWT auth with role-based access control, Docker multi-stage builds, GitHub Actions CI/CD. Live Swagger UI →

spring-boot-insights — API monitoring library Zero-config Spring Boot library published on Maven Central. Detects N+1 queries in real time via Hibernate's StatementInspector, live auto-refreshing dashboard for latency and query counts. Maven Central →

Order-Inventory Microservices — Distributed system Two independently deployable Spring Boot services with Eureka service discovery, OpenFeign inter-service calls, Redis cache-aside layer, and Resilience4j circuit breakers for graceful degradation.

Tech Stack

Java Spring Boot Spring Security Spring Cloud (Eureka, OpenFeign) Resilience4j Redis PostgreSQL MySQL Docker GitHub Actions JWT

Currently working on

  • OAuth2 (Google login) on ReserveShow — auth flow works, debugging the user persistence layer
  • DSA — pushing past Easy-heavy LeetCode ratio into Medium-level patterns
  • Docker Compose + AWS ECS Fargate for the microservices project
